Recently, the consuming efficiency of energy and natural resources has been a hot issue because of the continuous increasing of energy consumption and soaring of international oil prices. We tried to seek an action plan for the government's new paradigm 'Low-Carbon, Green Growth' by consuming energy efficiently and improving in energy management based on ubiquitous IT technologies. In this study, the library survey method is adopted for this study and IP-USN(internet protocol based ubiquitous sensor network) is considered as a core technology among various ubiquitous IT technologies. The purpose of this study is to deliver a method of energy management through integrating the context information gathered from sensors with digital space models and visualizing them together. The details are to survey the technologies of digital space modeling, USN based monitoring, building energy management and to integrate these technologies all together. This study will contribute to the enhancement of efficient building energy management by grasping the accurate situation of energy consuming in the building in realtime and minimizing unnecessary energy wastes.

The purpose of this paper is to predict the future changes of housing through the Delphi technique. The targets to predict were set by housing type, housing space, housing demand, and architectural technology. The results were as follows: ① The influences of social and value perspectives on the change of housing type, space, and demand would be high, on the other hands, the influence of political perspective would be low. ② In terms of housing type, the increase in demand for downsizing housing for high-rise buildings and the possibility of realizing remote medical support services and homecare using big data are highly predicted. That is, ③ it is anticipated that IoTs will have a significant influences on future housing changes, and ④ enactment of co-housing and related laws by the sharing economy, services for maintenance through the supply of high-rise and high-density homes, housing support for residents, and advanced lease markets by developed architectural technology are expected as anticipated forms of future housing.

최근 상업용 빌딩, 주거용 빌딩 및 공장등의 저전압 3상 4선식 배전계통에서 PC, UPS, 정류기기, 조명장치 및 사무용기기등 비선형 부하의 사용이 증가하고 있으며, 이로 인한 과도한 중성선 전류는 중성선의 고장, 변압기의 과열 및 중성선과 접지사이의 전압강하등 심각한 문제를 야기시키고 있다. 본 논문에서는 3상 4선식 배전계통에서 중성선 전류 저감을 위한 새로운 능동전력필터를 제안한다. 제안한 방식은 제어가 간단하고 부하용량대비 인버터등 장치의 용량이 작아 저가격으로 실현할 수 있다. 제안한 시스템은 이론적인 분석과 모의실험 및 실험에 의하여 그 타당성을 입증한다.

Since the Intelligent Building was first introduced in early 1980s, It has been studied and designed by related technical experts as it was called by the name of intelligent Building, High-tech Intelligence Building, High-capacity Building, Intellectual Building, etc. Despite the need for new concept as the relation between global environment and architecture has become an issue on a full scale since 1990s and with the development of high technology, former concept is maintained without modification or complement. Especially, attempt to combine industrial technology with architecture is essential to Intelligent Building, therefore frequent opportunity of self-innovation according to the development of technology is necessary. Due to the rarity of the high-technology and its high cost, it was adopted to large-scale construction, however, nowadays, almost all kinds of buildings are getting designed with intelligent-technology. Therefore we can expect that this trend will be accelerated by evolution of technology and will position as a major stream of future architecture along with environment-friendly architecture. Through this process, we should fully be aware of the importance of the several intelligent skin technology to protect global environment and to set future direction in architecture.

대도시의 인구집중에 따라 토지의 고도이용을 위하여 건물의 고층화 및 복합화에 대한 요구가 점점 더 높아지고 있으며, 도심지에서의 삶의 질을 윤택하게 하기 위한 방법으로서 조망에 대한 욕구가 더 한층 중요시되고 있다. 이러한 이유로 인해 주거용 아파트에도 초고층 빌딩 개념이 도입되고, 상가 및 커뮤니티 시설 등이 추가되는 주상복합건물의 건설이 증가하는 추세에 있다.(중략)

요즘 현대사회는 주거생활을 윤택하게 하기 위해 많은 노력을 기울이고 있다. 특히 지능형 빌딩 시스템이나 가정 자동화 등이 대표적인 예라 할 수 있다. 본 논문에서는 환경에 따라 자동 조절할 수 있는 창문제어장치를 구현하고 실험을 통해 그 신뢰성을 입증하였다. 실내 온도의 변화를 인지하여 창문의 개폐여부를 판정하고, 원격제어를 통해 조작이 가능하도록 거주자 편의에 중점을 두어 설계를 하였다.

In accordance with the implementation of the Zero Energy Building Certification System, it for the activation and expansion of the private sector is being steadily upgraded. Also The government has set up a step-by-step mandatory roadmap until it is expanded to the private sector, starting with the public sector. We analyzed the energy requirements of existing buildings from 2016 to 2017 and the by load relationships of major factor. Of the existing buildings, 714 buildings in central and southern areas excluding residential buildings such as apartments and officetels were classified and their primary energy requirements were analyzed. As new design technologies are applied, the demand for energy from the passive side is steadily declining. In addition, there is a need to interpret various methods to improve the zero energy building certification standard in the point that the zero energy building pilot project is continuously carried out in relation to the activation of renewable energy supply.

The Beautiful rest room is simple how to think. We need to understand that excretion is important as much as eating. When we didn't have foods, eating was important in itself no matter what our lives environments. But now we want to eat in more dignified and more cultural place. Most of restaurants spend money on adjusting place for the consumes' desire. It is same way about rest room, it is time to change our rest room to place of rest and speculation over the place which we fix our natural urge. We can fix our natural urge, take a rest, and get creative ideas in more convenient, more healthy and more comfortable. It is time for us to change out thought about rest room; it is not dirty and stink place, but civilized living place like developed country. Also, we need new concept to take a triangular position about rest room is one of structure over just decorations. This research suggest new public rest room without precedent based on instance analysis about rest room inside and outside the country.

저번 회에서는 Barclays Center의 그린루프의 디자인 과정을 개략적으로 살펴보았습니다. 소음 저감의 목적으로 인하여 도출되었던 두 가지의 변수(새로운 루프의 중량과 두 겹의 루프사이에 위치하는 빈 공간)및 기존의 바클레이 센터가 가지고 있는 물리적인 특성(파라펫 및 기존 루프의 형상)을 고려하여 design surface를 설정하였고, 중량에 대한 조건 및 주변의 고층 주거빌딩들로 인해 일반적인 루프와는 다른 미적인 특이성을 고려하여 그린 루프라는 큰 방향을 제시하고, 양방향 곡면의 특성을 가지는 루프의 지오메트리와 시공 상의 복잡함과 공기의 단축을 위해 모듈로 이루어진 시스템을 제안하게 되었습니다. 이번 회에서는 루프의 디자인을 진행함에 있어서 어떠한 제약 조건이 있었으며 그러한 제약 조건들이 최종적인 루프 디자인 및 패턴에 어떠한 영향을 미쳤는지, 그리고 이러한 과정에서 파라메트릭 툴이 어떻게 사용되었는지에 대해 자세히 살펴보도록 하겠습니다. 이어서 다음 회에서는 디자인 측면에서가 아닌 pre-construction의 측면에서 시공상의 시행착오를 줄이고 공기를 단축하기 위한 목적으로 파라메트릭 툴의 사용하여 시뮬레이션을 했던 과정에 대해 자세히 알아보도록 하겠습니다.
